Big Blue® & Big Clear Filter Housings
Remove unwanted minerals from your water to improve solubility.
How It Works
Big Blue® Filter Housings offer the versatility to meet all of your large-capacity filtration needs, including high-flow and heavy-sediment applications. The extra large housing allows for greater cartridge capacity, reducing the number of vessels required for high flow-rate applications. Sumps are constructed of durable reinforced polypropylene and are available in both 10″ and 20″ lengths.
The high-flow polypropylene (HFPP) cap is available with 3/4″, 1″ or 1½” NPT inlet and outlet ports. The 1¼” internal port allows a greater volume of liquid to pass through the HFPP cap more rapidly.
Big Blue® housings are compatible with a broad range of chemicals and are available with or without a pressure relief button. They accept a wide variety of 4½” diameter cartridges.
Big Clear Filter Housings offer on-site examination of flow, performance, and cartridge life and are ideal for a variety of applications. The blue polypropylene caps are available with an optional pressure-relief button on the inlet side to relieve pressure inside the housing when changing filter cartridges.
